HUB CONSTRUCTION FOR DEMOUNTABLE WHEELS.

Application filed July 28,

My invention relates to improvements in demountable wheels for motor vehicles, said F Improvements having special reference to the construction of motor vehicle hubs for s the reception of demountable wheels. And

more especiall my invention relates to improvements which shall particularl adapt such hubs for the reception of whee s of the demountable types disclosed in my former Patents 1,321,000-1, and 1,334,011. Such wheels, and some others, are characterized a wooden hub center portion which is 0 am ed against the bac flange of the meta hub of the vehicle by means of a plull rality of hub bolts. e arrangement of these bolts in the flanges of the driving hubs is attended with considerable difliculty, the construction being complicated b the presence of the brake drums. The difficulty is so further accentuated when the hubs are of the kinds used with floating and semi-floatin axles.

The object of this invention is to rovide a hub construction peculiarly adapt to demountable wheels and of a universal order concerning the several types of hubs used with live, floating, and semi-floating axles.

y invention comprises a novel wheel hub of the construction and combination of Farts hereinafter described and particuarly pointed out in the appended claims;

and, will be readily understood on reference to the accompanying drawings which form a part of this specification in which Fig. 1 is a sectional view of the axle, hub and wheel embodying my invention.

Fig. 2 is a vertical detail sectional view through a part of the brake drum showing the manner of securing a certain nut therein.

Fig. 3 is a vertical detail sectional view through that portion of the back flan e of the hub associated with that part 0 the brake drum shown in Fig. 2.

Fig. 2 is a vertical detail sectional view through another part of the brake drum with which another part of the hub flange en ages.

ig. 3" is a vertical detail sectional view through that portion of the back flange of the hub associated with that part of the brake drum shown in Fi 2'.

Fig. 4 is a view in si e elevation of one means which may be used to detachably secure together, that part of the brake drum 1822. Serial No. 578,158.

and that part of the back flange shown in lie. 2" and 3", respective] t the beginning it shoul d be understood that this invention is not limited to any particular demountable wheel except in so for as the demountable wheel W is of a kind to be secured to the vehicle by a plurality of hub bolts 2. The particular wheel shown in these drawings will be found in Letters Patent 1,334,011 and does not require extended description herein. Similarl the combined center sleeve and outer flange W here illustrated, will be found in my ending application Serial, No. 608,613. As stated my invention is applicable to motor vehicle axles of all types; but, as being Suflicient for the or osesof this inventionI have restricted the illustration to a socalled floating axle construction, wherein every part of my present invention, including the brake drum, has'a direct operative relation.

Referring to Fig. 1, which best shows all of the detal 3 represents the floating axle, 4 the axle housing, 5 the fixed sleeve of the brake hanger (not shown), 6 the stop nut on the end of the housing 4, and 7 the inner ring of the ball hearing which ring is held between the arts 5 and 6. The outer rings 8 and the b s 9 are of usual construction;

goes without sayin that this p a ll bearing is me y exemplary of any bearing that may be used. packin 10 is also of usual construction. The ub H receives the end of the floatmg axle 3 and the anti-friction bearing described; and is characterized by an integral back flange 11 and a cylindrical barrel portion 12. be hearing is held between the internal shoulder 13 and the brake to drum 14, which latter is secured against the inner side of the flange 11 by the means about to be described.

As shown, the wheel fits over the barrel portion 12 of the hub and a ainst the outer face of the hub flange 11. t is secured in that position by the before-mentioned hub bolts 2, which pass through the outer hub flan e W, through the hub center portion of tie wheel, and into nuts 15, which nuts may be made of any desired meta], better than that composing the hub H. The nut 15 in its best form comprises the c lindrical body portion 15' containing the internal thread 15 for the hub bolt. It has the ex- 110 ternal thread 15" for the reception of the brake drum; and is provided with the stop flan e or collar 15 the ed e of which is re erablyoctagonal to faci 'tate the placin of the nut in the brake drum.

e brake drum contains as many holes as there are hub bolts 2, and these holes are threaded to receive the threads 15 of reective nuts 15. The nuts are screwed tight therein. The brake drum thus equi pad with the nuts is placed against the ubflange 11, which latter contains the openings 16 shaped to receive the parts 15' and 15 and hence each presenting a stop shoulder 16. When thuspositioned on the flange 11 with the nuts pro fierlly sunk in the shoulder openings 16, the ra e drum is secured or locked to the hub flange by means of one or more short screws or rivets 17 As will be apparent the hub bolts 2 when driven home in the nuts 15 serve to bind the wheel, the hub flan e drum so firmly together at they cannot be dislaced or di odged except by the intentional oosening of the hub bolts 2.

Thus secured the brake drum incidentally serves to fasten in place the anti-friction bearin of the floating axle, as before explaine and the hub can only be removed from the axle by first demounting the wheel and afterward removing the locking screws e, and the brak Those skilled in the art will immediately understand that ahub designed for use upon a live axle may have its rake drums permanently riveted to its back flange; thereby avoiding the use of the locking screws 17, which according to m invention, are typical of a hub identified with a floating axle or a semi-floating axle.

A particular novel feature to which call attention, comprises the center Slllk which I provide in the brake drum whereby the latter is provided with a centering shoulder 14 for co-action with the periphery of the hub flange 11, and an oflset outer portion whifih may rest directly against the wheel In its entirety my improved hub is admirably suited to fill every requirement concerning the driving axle, the wheel, and the brake drum, and will be found to be much stronger, more convenient, and of less weight and cost than the several vehicle hubs in present use.
